Description

Technical Field

[0001] The present disclosure generally relates to the field of range extender suspension, and in particular to a range extender suspension limit device. Background Art

[0002] The range extender assembly is connected and fixed to the vehicle body through the suspension system, and the suspension system is responsible for supporting the range extender assembly.

[0003] At present, the full life working conditions of vehicles can be roughly divided into normal working conditions, normal extreme working conditions, misuse working conditions, collision working conditions, etc. according to the severity. Normal working conditions, normal extreme working conditions, normal misuse working conditions, and normal collision working conditions require that the range extender suspension cannot be damaged. Extreme misuse working conditions (such as 50km / h over a speed bump and falling into a pit) allow the range extender suspension to be damaged. Extreme collision working conditions (such as high-speed head-on collision) do not require the degree of suspension damage. In the actual use of users, it is inevitable to trigger the misuse working condition. For those that reach the normal misuse working condition conditions, the suspension system must provide sufficient limit to limit the large swing of the range extender assembly and interfere with the surrounding parts, causing damage to the parts. At the same time, protect the suspension parts themselves from damage; when reaching the extreme misuse working condition, the suspension parts body may break, fall off, and the rubber may be torn off. After damage, the suspension system should provide limit to ensure that the range extender assembly does not fall, thereby avoiding major damage to the range extender assembly or the vehicle body.

[0004] The existing range extender suspension device only has limit devices in the X-axis and Z-axis directions of the vehicle, and there is no limit device to limit in the direction parallel to the wheel rotation axis; when the rubber of the suspension structure ages or breaks, the limiting effect of the range extender will be lost, which may easily cause the range extender to fall off or be damaged.

[0048] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0049] In the prior art, reference Figure 1 ,When describing the direction of a car, the X-axis, Y-axis and Z-axis of the car are usually used. Specifically, the X-axis direction of the car refers to the direction in which the car moves normally, the Y-axis direction of the car refers to the direction parallel to the axis of rotation of the wheel, and the Z-axis direction refers to the vertical direction.

[0050] The existing automobile range extender suspension structure only connects the range extender and the vibration absorber through a suspension bracket. One end of the vibration absorber is connected to the suspension bracket, and the other end is installed on the frame assembly through a connecting structure. This type of connection method can only limit the suspension bracket in the X-axis and Z-axis directions, and it is difficult to limit it in the Y-axis direction; as the use time increases, the rubber material inside the vibration absorber will age and break. At this time, once the range extender starts to vibrate, the irregular vibration direction will cause the suspension bracket to move in the Y-axis direction, which will cause the suspension bracket to fall off from the range extender, causing danger.

[0051] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0052] Example 1

[0053] Please refer to Figure 1 and Figure 2, is a schematic diagram of a range extender suspension limiter provided in this embodiment, which is used to restrict the range extender from moving in a first direction perpendicular to the first direction, wherein the first direction is parallel to the normal traveling direction of the vehicle, and specifically includes:

[0054] A suspension body 5, wherein the suspension body 5 is mounted on the vehicle frame assembly and is used to connect the vehicle frame assembly and the range extender;

[0055] A mounting frame 1, wherein the mounting frame 1 is mounted on the suspension body 5;

[0056] A first connecting member 2, wherein the first connecting member 2 is provided with a limited position through hole 6 along a first direction; the first connecting member 2 has a first connecting end and a second connecting end, wherein the first connecting end is used for fixedly connecting the range extender, and the second connecting end is used for connecting the suspension body 5;

[0057] a limiting rod 3, the limiting rod 3 being arranged parallel to the first direction, passing through the limiting through hole 6 and having both ends respectively fixedly mounted on the mounting frame 1; the limiting rod 3 being used to limit the first connecting member 2 perpendicular to the first direction;

[0058] The second connecting member 4 has one end mounted on the suspension body 5 and the other end fixedly connected to the first connecting member 2 ; the second connecting member 4 is used for fixedly connecting the suspension body 5 and the first connecting member 2 .

[0059] Specifically, the first direction is the X-axis direction of the vehicle; the limiting rod 3 is used to limit the first connecting member 2 along the Y-axis and Z-axis directions of the vehicle.

[0060] in, Figure 1 One end of the middle suspension body 5 is installed on the automobile frame assembly by bolt connection. The middle part of the suspension body 5 has a rubber bushing, and the rubber bushing is fixedly connected to the first connecting member 2; the first connecting member 2 is fixedly connected to the range extender by bolts. When the range extender is started and vibrates, the first connecting member 2 moves in any direction with the range extender.

[0061] When the first connecting member 2 vibrates along the X-axis and Z-axis directions of the vehicle, it will abut against the rubber bushing. Since the rubber bushing is fixedly installed on the vehicle frame assembly along with the suspension body 5, the rubber bushing can limit the first connecting member 2 and the range extender connected thereto along the X-axis and Z-axis directions of the vehicle.

[0062] A mounting frame 1 is added to the suspension body 5, and a limiting rod 3 is installed on the mounting frame 1. A limiting through hole 6 is provided on the first connecting member 2, and the limiting rod 3 passes through the limiting through hole 6. When the first connecting member 2 vibrates along the Y-axis direction of the vehicle along with the range extender, the outer wall of the limiting rod 3 abuts against the inner wall of the limiting through hole 6 to limit the first connecting member 2. Therefore, the limiting rod 3 can effectively limit the vibration of the range extender along the Y-axis direction; when the rubber bushing on the suspension body 5 ages and fails, the limiting rod 3 abuts against the limiting through hole, which can prevent the range extender from being separated from the vehicle frame assembly, thereby improving the structural stability of the range extender.

[0063] In some embodiments, the first connector 2 is assembled and formed by two materials: cast iron and cast aluminum. The side of the first connector 2 where the limiting through hole 6 is opened is made of cast iron material; the end of the first connector 2 connected to the second connector 4 is made of cast aluminum material, and the structural strength is the weakest. When encountering extreme working conditions, the end of the first connector 2 connected to the second connector 4 will break first; at this time, the inner side wall of the limiting through hole 6 abuts against the outer surface of the limiting rod 3; the limiting rod 3 will have a limiting effect on the first connector 2, ensuring that the range extender will not fall off, improving the stability of the suspension structure, and ensuring the safety of the range extender under extreme working conditions.

[0064] In some embodiments, two mounting brackets 1 are provided on the suspension structures on both sides of the vehicle range extender; and a limit rod 3 passing through the limit through hole 6 is installed between the mounting brackets 1. The limit rods 3 are installed on both suspension sides, and when the range extender generates obvious vibration, the limit rods 3 will abut against the inner side wall of the limit through hole 6; because both ends of the limit rod 3 are fixedly connected to the mounting bracket 1, the mounting bracket 1 is fixedly connected to the frame assembly through the suspension body. Therefore, the limit rod 3 can maintain a relatively fixed position with the frame assembly, and then can limit the range extender perpendicular to the first direction, thereby ensuring the safety of the range extender.

[0065] Furthermore, the limiting rod 3 comprises:

[0066] A limiting sleeve, the limiting sleeve is arranged along the first direction, a mounting through hole is provided inside the limiting sleeve and passes through the limiting sleeve along the first direction, and limiting raised rings 7 are installed at both ends;

[0067] A limiting bolt passes through the mounting through hole and has two ends fixedly connected to the mounting frame 1 respectively.

[0068] In some embodiments, when the limiting rod 3 is limiting the first connecting member 2, the inner side wall of the limiting through hole 6 will abut against the outer side wall of the limiting rod 3; during long-term movement, the abutment and collision will cause wear on the limiting rod 3 and the first connecting member 2. The limiting rod 3 is designed as a limiting sleeve and a limiting bolt. The limiting bolt is used to pass through the limiting sleeve, and the two ends are fixedly connected to the two mounting frames 1 by nuts. When the limiting bolt passes through the limiting sleeve and is fixedly connected to the mounting frame 1, the mounting frame 1 will abut against the two ends of the limiting sleeve under the abutment of the nuts on both sides, and then clamp the limiting sleeve along the X-axis direction of the vehicle, and finally realize the installation of the limiting rod 3, so that the limiting rod 3 can produce a limiting effect on the first connecting member 2.

[0069] When the two are in contact, the inner wall of the limiting through hole 6 is in contact with the outer wall of the limiting sleeve; in the process of limiting the first connecting member 2, direct contact and wear between the first connecting member 2 and the limiting bolt can be avoided, thereby improving the service life.

[0070] Further, refer to Figure 4 The radius of the limiting through hole 6 is greater than the radius of the limiting rod 3, and a limiting space is formed between the limiting through hole 6 and the limiting rod 3; an abutment 8 is provided in the limiting space; the abutment 8 is sleeved on the limiting rod 3, and a gap is left between the abutment 8 and the limiting through hole 6; the abutment 8 is used to abut against the inner side wall of the limiting through hole 6 to limit the first connecting member 2 perpendicular to the first direction.

[0071] In some embodiments, the abutment member 8 is disposed in the limiting space and fixedly connected to the outer side wall of the limiting rod 3 ; a gap is left between the abutment member 8 and the limiting through hole 6 .

[0072] Specifically, abutment 8 is provided in the limiting space; when the limiting through hole 6 and the limiting sleeve generate relative movement, the inner side wall of the limiting through hole 6 abuts against the abutment 8, and the abutment 8 is made of rubber material, which can play a buffering role in the process of abutment between the first connecting member 2 and the limiting rod 3, reduce the impact force, reduce the wear of the limiting rod 3, and improve the service life.

[0073] Furthermore, the radius of the limiting through hole 6 is greater than the radius of the limiting rod 3, and a limiting space is formed between the limiting through hole 6 and the limiting rod 3; an abutment 8 is provided in the limiting space; the abutment 8 is sleeved on the limiting rod 3 and abuts against the inner side wall of the limiting through hole 6; the abutment 8 is used to limit the first connecting member 2 perpendicular to the first direction.

[0074] In some embodiments, the abutment 8 is connected to the limit rod 3 and the limit through hole 6, respectively. When the range extender vibrates, the first connection member 2 is driven to vibrate, and the limit through hole 6 and the limit rod 3 generate relative motion; at this time, since the limit through hole 6 is connected to the abutment 8, the limit through hole 6 will compress the abutment 8 and will not cause collision. At the same time, by utilizing the easy deformation characteristics of rubber material, the collision during the limit can be eliminated, further improving the limit effect.

[0075] Further, refer to Figure 3 , the second connecting end of the first connecting member 2 is provided with a connecting hole 9;

[0076] The second connecting member 4 has a first connecting portion and a second connecting portion; the first connecting portion is fixedly installed in the connecting hole 9 , and the second connecting portion is fixedly connected to the suspension body 5 .

[0077] In some embodiments, the first connecting member 2 is provided with a connecting hole 9, and is connected to the suspension body 5 through the second connecting member 4. By connecting the second connecting member 4 to the suspension body 5, the suspension body 5 and the first connecting member 2 can be conveniently connected. At the same time, when the rubber bushing of the suspension body 5 or the second connecting member is broken, the limiting rod 3 limits the first connecting member 2. Only the rubber bushing or the second connecting member 4 needs to be replaced, and the first connecting member 2 does not need to be replaced together; the number of replacement parts can be reduced, and the cost can be reduced.

[0078] For specific application scenarios in the above embodiments, please refer to Figure 6 As shown, Figure 6 The schematic flow chart of the method for installing the range extender suspension limit device provided in this embodiment includes:

[0079] S1: Control the limiting sleeve to extend into the limiting through hole 6 so that the center of mass of the limiting sleeve is located in the central space of the limiting through hole 6; a mounting through hole is provided inside the limiting sleeve and penetrates the limiting sleeve along the first direction;

[0080] S2: Install the first connecting member 2 onto the suspension body 5; the limiting sleeve is installed between the two mounting frames 1 along with the first connecting member 2 parallel to the first direction;

[0081] S3: Install the limiting bolt into the installation through hole, and fix the two ends to the two installation frames 1 respectively.

[0082] Specifically, the suspension limit device provided by the present application is provided by opening a limit hole 6 in the first connecting member 2 along the direction of the X-axis of the vehicle; extending the limit rod 3 into the limit hole 6; at the same time, the two ends of the limit rod 3 are respectively fixedly connected to the two mounting frames 1, and when the vibration amplitude of the range extender is large, the range extender will drive the first connecting member 2 to vibrate together. The technical concept of the present application is that the mounting frame 1 and the limit rod 3 fixedly connected to the frame assembly are limited in the direction perpendicular to the X-axis of the vehicle by the limit rod 3 abutting against the inner side wall of the limit hole 6; since the first connecting member 2 is fixedly connected to the range extender, the range extender is limited in the direction of the X-axis of the vehicle.

[0083] This type of nested connection cannot be installed in any order because of the interference between the parts. Therefore, a specific assembly order is required. Figure 6 The steps shown are as follows: first, the limiting sleeve is controlled to extend into the limiting through hole 6, and then the limiting protruding ring 7 is installed to both ends of the limiting sleeve; at this time, under the action of the limiting protruding ring 7, the limiting sleeve and the first connecting member 2 can maintain a relative fixed position; in the process of installing the first connecting member 2 to the suspension body 5, the limiting sleeve will move with the first connecting member 2 to the space between the two mounting frames 1, and in the process of adjusting the direction of the first connecting member 2, the opening direction of the limiting through hole 6 is made parallel to the X-axis direction of the vehicle; since the limiting sleeve has been installed in the limiting through hole 6, the limiting sleeve will have a very small angle with the X-axis direction of the vehicle, and in the process of extending the limiting bolt into the limiting sleeve, the outer wall of the limiting bolt abuts against the inner wall of the limiting sleeve, thereby realizing further correction of the reverse direction of the limiting sleeve. Through the above splicing sequence, the installation process of the entire suspension structure can be correctly completed without generating motion interference between structures; thereby realizing the limiting effect of the suspension structure provided in the present application on the range extender perpendicular to the X-axis direction of the vehicle.

[0084] In some embodiments, the limiting sleeve is extended into the limiting through hole 6, and then the first connecting member 2 with the limiting sleeve is placed between the two mounting frames 1, so that the second connecting member 4 connects the suspension body 5 and a connecting member 2, so that the two ends of the limiting sleeve are respectively abutted against the two mounting frames 1; and then the limiting bolt is passed through the mounting frame 1 on one side, the mounting through hole, and the mounting frame 1 at the other end at one time, and fixed with a nut.

[0085] In some embodiments, after the limiting rod 3 is extended into the limiting through hole 6, limiting protrusion rings 7 are provided at both ends of the limiting rod 3, which can limit the first connecting member 2 along the first direction and prevent the first connecting member 2 from falling off during installation.

[0086] Furthermore, based on the range extender suspension limiter described in the above embodiment,

[0087] After the control limiting sleeve extends into the limiting through hole 6 so that the center of mass of the limiting sleeve is located in the central space of the limiting through hole 6, and before the first connecting member 2 is installed on the suspension body 5, the method further includes:

[0088] The limiting protrusion rings 7 are installed to both ends of the limiting sleeve.

[0089] In some embodiments, before the control limit sleeve is extended into the limit through hole 6, limit protrusion rings 7 are installed at both ends of the limit sleeve, so that the limit protrusion rings 7 abut against the mounting frames 1 on both sides, thereby generating static friction between the limit protrusion rings 7 and the mounting frame 1. The static friction is used to keep the limit sleeve and the mounting frame 1 in a relatively fixed position, which facilitates the limit bolt to extend into the mounting through hole and improves the installation efficiency.

[0090] Further, the radius of the limiting through hole 6 is greater than the radius of the limiting rod 3, and a limiting space is formed between the limiting through hole 6 and the limiting rod 3; an abutment member 8 is provided in the limiting space; and the thickness between the inner wall and the outer wall of the abutment member 8 is equal to the difference between the radius of the limiting through hole 6 and the radius of the limiting rod 3;

[0091] Before the step of controlling the limiting sleeve to extend into the limiting through hole 6, the method further includes: controlling the abutment member 8 to be sleeved on the limiting rod 3 so that the inner side wall of the abutment member 8 abuts against the outer side wall of the limiting rod 3;

[0092] After the step of controlling the limiting sleeve to extend into the limiting through hole 6 is performed, the outer wall of the abutment member 8 abuts against the inner wall of the limiting through hole 6; the abutment member 8 is used to limit the first connecting member 2 perpendicular to the first direction.

[0093] In some embodiments, the two sides of the abutment 8 connect the limiting through hole 6 and the limiting sleeve; the thickness of the abutment 8 is equal to the radius difference between the limiting through hole 6 and the limiting sleeve. When the limiting through hole 6 and the limiting sleeve produce relative motion, the inner side wall of the limiting through hole 6 abuts against the abutment 8. The abutment 8 is made of rubber material and can play a buffering role in the process of the first connecting member 2 abutting against the limiting rod 3. The sleeve of the abutment 8 can fix the relative position of the first connecting member 2 and the limiting sleeve during installation, which is convenient for installation.

[0094] Further, the radius of the limiting through hole 6 is greater than the radius of the limiting rod 3, and a limiting space is formed between the limiting through hole 6 and the limiting rod 3; an abutment member 8 is provided in the limiting space; and the thickness between the inner wall and the outer wall of the abutment member 8 is less than the difference between the radius of the limiting through hole 6 and the radius of the limiting rod 3;

[0095] Before the step of controlling the limiting sleeve to extend into the limiting through hole 6, the method further includes: controlling the abutment member 8 to be sleeved on the limiting rod 3 so that the inner side wall of the abutment member 8 abuts against the outer side wall of the limiting rod 3;

[0096] After the step of controlling the limiting sleeve to extend into the limiting through hole 6, a gap is left between the outer wall of the abutment 8 and the inner wall of the limiting through hole 6; the abutment 8 is used to abut against the inner wall of the limiting through hole 6 when the range extender vibrates, thereby limiting the first connecting member 2 perpendicular to the first direction.

[0097] Specifically, the abutment 8 is installed on the mounting frame 1 and remains relatively still with the vehicle body through the suspension body 5; when the range extender vibrates, it will drive the first connecting member 2 to vibrate in all directions, thereby generating a displacement relative to the vehicle body, and generating a relative displacement between the first connecting member 2 and the limiting rod 3; when the displacement reaches the gap width, the abutment 8 abuts against the inner side wall of the limiting through hole, generating a limiting effect.

[0098] Further, refer to Figure 5 , based on the range extender suspension limiter device described in the above embodiment,

[0099] Before the control limiting sleeve extends into the limiting through hole 6 so that the center of mass of the limiting sleeve is located in the central space of the limiting through hole 6, the method further includes:

[0100] An auxiliary mounting member 10 is sleeved on the outer side wall of the limiting sleeve; the auxiliary mounting member 10 is arranged at both ends of the abutting member 8 and abuts against the inner side wall of the limiting through hole 6, and is used to fix the relative position of the first connecting member 2 and the limiting sleeve;

[0101] After the step of installing the limiting bolt into the installation through hole and fixing both ends of the bolt to the two installation frames 1 respectively, the step further includes: controlling the auxiliary installation member 10 to be separated from the limiting space.

[0102] In some embodiments, when the thickness of the abutment member 8 is smaller than the radius difference between the limiting through hole 6 and the limiting sleeve, an auxiliary mounting member 10 is sleeved on the outer wall of the limiting sleeve. After installation, the inner wall of the auxiliary mounting member 10 abuts against the limiting sleeve, and the outer wall abuts against the limiting through hole 6, which is convenient for fixing the relative position of the first connecting member 2 and the limiting sleeve during installation; an opening is provided on the auxiliary mounting member 10, and when the auxiliary mounting member 10 is removed, it is convenient for the limiting sleeve to be detached from the auxiliary mounting member 10 from the opening.
